Determining the Impact of Line Asymmetries on Network Voltage Unbalance based on Balanced Load Flow Studies

Australasian Universities Power Engineering Conference, 2018
Determining the impact of the individual contributors to network voltage unbalance (VU) is a complex task due to the interaction between the sources of voltage unbalance in power systems. This becomes further complicated as the network itself contributes

Diagnosis of voltage unbalance state in a system with power converter

Diagnostyka
In the paper problem of power supply unbalance voltage states with the same Voltage Unbalance Factor (VUF) value for power converters is tackled. This factor is being used to assess the quality of power supply. There are many sources of voltage unbalance

On the Assessment of Three-Phase Delta Voltages’ Unbalance

2020 Moscow Workshop on Electronic and Networking Technologies (MWENT), 2020
Several existing three-phase delta voltages’ unbalance factors, including the "true unbalance factor" (the negative sequence voltage unbalance factor) and its complex form, are considered.

Zero Sequence Voltage Phasor Positioning under Balanced Three-Phase Supply

2019 International Ural Conference on Electrical Power Engineering (UralCon), 2019
Based on the representations in barycentric coordinates on a balanced supply line-to-line voltages triangle the resulting complex-plane static phasors of the zero sequence voltage and of the related unbalance factor are obtained for the balanced mode of ...
